Commission.
ACTION: Direct final rule.
AGENCY:
The U.S. Nuclear Regulatory
Commission (NRC) is amending its
spent fuel storage regulations by
revising the NAC International, Inc.
MAGNASTOR® Storage System listing
within the ‘‘List of approved spent fuel
storage casks’’ to include Amendment
No. 13 to Certificate of Compliance No.
1031. Amendment No. 13 revises the
certificate of compliance to add a new
type of radioactive contents to be stored
inside the MAGNASTOR® transportable
storage canister, add a new design
configuration for the canister to
accommodate the fuel bearing material
and new canister components, and use
an alternate compressive strength for
concrete cask no. 6 of 6,000 psi.
DATES: This direct final rule is effective
November 19, 2024, unless significant
adverse comments are received by
October 7, 2024. If this direct final rule
is withdrawn as a result of such
comments, timely notice of the
withdrawal will be published in the
Federal Register. Comments received
after this date will be considered if it is
practical to do so, but the NRC is able
to ensure consideration only for
comments received on or before this
date. Comments received on this direct
final rule will also be considered to be

II. Rulemaking Procedure
This rule is limited to the changes
contained in Amendment No. 13 to
Certificate of Compliance No. 1031 and
does not include other aspects of the
NAC International, Inc. MAGNASTOR®
Storage System design. The NRC is
using the ‘‘direct final rule procedure’’
to issue this amendment because it
represents a limited and routine change
to an existing certificate of compliance
that is expected to be non-controversial.
Adequate protection of public health
and safety continues to be reasonably
assured. The amendment to the rule will
become effective on November 19, 2024.
However, if the NRC receives any
significant adverse comment on this
direct final rule by October 7, 2024, then
the NRC will publish a document that
withdraws this action and will
subsequently address the comments
received in a final rule as a response to
the companion proposed rule published
in the Proposed Rules section of this
issue of the Federal Register or as
otherwise appropriate. In general,
absent significant modifications to the
proposed revisions requiring
republication, the NRC will not initiate
a second comment period on this action.
A significant adverse comment is a
comment where the commenter
explains why the rule would be
inappropriate, including challenges to
the rule’s underlying premise or
approach, or would be ineffective or
unacceptable without a change. A
comment is adverse and significant if:
(1) The comment opposes the rule and
provides a reason sufficient to require a
substantive response in a notice-andcomment process. For example, a
substantive response is required when:
(a) The comment causes the NRC to
reevaluate (or reconsider) its position or
conduct additional analysis;
(b) The comment raises an issue
serious enough to warrant a substantive
response to clarify or complete the
record; or
(c) The comment raises a relevant
issue that was not previously addressed
or considered by the NRC.
(2) The comment proposes a change
or an addition to the rule, and it is
apparent that the rule would be
ineffective or unacceptable without
incorporation of the change or addition.
(3) The comment causes the NRC to
make a change (other than editorial) to
the rule, certificate of compliance, or
technical specifications.
III. Background
Section 218(a) of the Nuclear Waste
Policy Act of 1982, as amended,
requires that ‘‘[t]he Secretary [of the
VerDate Sep<11>2014
21:04 Sep 04, 2024
Jkt 262001
Department of Energy] shall establish a
demonstration program, in cooperation
with the private sector, for the dry
storage of spent nuclear fuel at civilian
nuclear power reactor sites, with the
objective of establishing one or more
technologies that the [Nuclear
Regulatory] Commission may, by rule,
approve for use at the sites of civilian
nuclear power reactors without, to the
maximum extent practicable, the need
for additional site-specific approvals by
the Commission.’’ Section 133 of the
Nuclear Waste Policy Act states, in part,
that ‘‘[t]he Commission shall, by rule,
establish procedures for the licensing of
any technology approved by the
Commission under Section 219(a) [sic:
218(a)] for use at the site of any civilian
nuclear power reactor.’’
To implement this mandate, the
Commission approved dry storage of
spent nuclear fuel in NRC-approved
casks under a general license by
publishing a final rule that added a new
subpart K in part 72 of title 10 of the
Code of Federal Regulations (10 CFR)
entitled ‘‘General License for Storage of
Spent Fuel at Power Reactor Sites’’ (55
FR 29181; July 18, 1990). This rule also
established a new subpart L in 10 CFR
part 72 entitled ‘‘Approval of Spent Fuel
Storage Casks,’’ which contains
procedures and criteria for obtaining
NRC approval of spent fuel storage cask
designs. The NRC subsequently issued a
final rule on November 21, 2008 (73 FR
70587), that approved the NAC
International, Inc. MAGNASTOR®
Storage System design and added it to
the list of NRC-approved cask designs in
§ 72.214 as Certificate of Compliance
No. 1031.
IV. Discussion of Changes
On July 13, 2022, NAC International,
Inc. submitted a request to the NRC to
amend Certificate of Compliance No.
1031. NAC International, Inc. and
supplemented its request on the
following dates: October 13, 2022,
November 30, 2022, June 27, 2023,
August 17, 2023, and September 15,
2023 (ADAMS Accession Nos.
ML22287A038, ML22321A269,
ML23178A225, ML23229A481, and
ML23258A233, respectively).
Amendment No. 13 revises the
certificate of compliance to add a new
type of radioactive contents (fuel
bearing material (FBM) from the
damaged Three Mile Island Unit 2
reactor) to be stored inside the
MAGNASTOR® transportable storage
canister (TSC) and to include concrete
with a compressive strength of 6,000 psi
for concrete cask number 6 as an
alternate to the previously approved
8,000 psi compressive strength.
PO 00000
Frm 00002
Fmt 4700
Sfmt 4700
Additionally, Amendment No. 13 adds
a new design configuration of the TSC
(the FBM TSC) to accommodate the
FBM and the TSC internal components.
The new configuration includes: (1)
reducing closure lid assembly thickness
of the TSC and removing the hydrostatic
pressure test; (2) adding a new waste
basket liner (WBL) (based on the
Greater-Than-Class C Waste WBL) made
from stainless steel in lieu of the fuel
basket for the storage of FBM inside the
FBM TSC; (3) adding a new debris
material container to be used as an
operational device to handle and house
finer debris; and (4) adding a new
segmented tube assembly to define cells
for loading.
As documented in the preliminary
safety evaluation report, the NRC
performed a safety evaluation of the
proposed certificate of compliance
amendment request. The NRC
determined that this amendment does
not reflect a significant change in design
or fabrication of the cask. Specifically,
the NRC determined that the design of
the cask would continue to maintain
confinement, shielding, and criticality
control in the event of each evaluated
accident condition. In addition, any
resulting occupational exposure or
offsite dose rates from the
implementation of Amendment No. 13
would remain well within the limits
specified by 10 CFR part 20, ‘‘Standards
for Protection Against Radiation.’’
Therefore, the NRC found there will be
no significant change in the types or
amounts of any effluent released, no
significant increase in the individual or
cumulative radiation exposure, and no
significant increase in the potential for
or consequences from radiological
accidents.
The NRC staff determined that the
amended NAC International, Inc.
MAGNASTOR® Storage cask design,
when used under the conditions
specified in the certificate of
compliance, the technical
specifications, and the NRC’s
regulations, will meet the requirements
of 10 CFR part 72; therefore, adequate
protection of public health and safety
will continue to be reasonably assured.
When this direct final rule becomes
effective, persons who hold a general
license under § 72.210 may, consistent
with the license conditions under
§ 72.212, load spent nuclear fuel, in the
form of FBM, into NAC International,
Inc. MAGNASTOR® Storage System
cask design that meet the criteria of
Amendment No. 13 to Certificate of
Compliance No. 1031.
The NRC is clarifying that
Amendment 13 to Certificate of
Compliance No. 1031 does not involve
E:\FR\FM\05SER1.SGM
05SER1
Federal Register / Vol. 89, No. 172 / Thursday, September 5, 2024 / Rules and Regulations
storage of spent fuel assemblies as is the
case for most certificate of compliance
applications. Rather, this amendment
involves storage of FBM, which
includes components associated with
deposited fuel and fission products from
the damaged Three Mile Island Unit 2
reactor, inside the transportable storage
canister. This amendment also involves
adding a new design configuration of
the transportable storage canister to
accommodate the FBM and the new
transportable storage canister internal
components. A waste basket liner is
proposed to replace the fuel basket
structure for storage of FBM. Because
this configuration involves only
deposited fuel and fission products
rather than entire spent fuel assemblies,
the storage of the materials is of lower
risk significance than that of the storage
of spent fuel assemblies. The NRC’s
safety evaluation considered the design
changes proposed for this amendment
and concluded that they meet the
requirements of 10 CFR part 72.
khammond on DSKJM1Z7X2PROD with RULES
V. Voluntary Consensus Standards
The National Technology Transfer
and Advancement Act of 1995 (Pub. L.
104–113) requires that Federal agencies
use technical standards that are
developed or adopted by voluntary
consensus standards bodies unless the
use of such a standard is inconsistent
with applicable law or otherwise
impractical. In this direct final rule, the
NRC revises the NAC International, Inc.
MAGNASTOR® Storage Cask System
design listed in § 72.214, ‘‘List of
approved spent fuel storage casks.’’ This
action does not constitute the
establishment of a standard that
contains generally applicable
requirements.
VI. Agreement State Compatibility
Under the ‘‘Agreement State Program
Policy Statement’’ approved by the
Commission on October 2, 2017, and
published in the Federal Register on
October 18, 2017 (82 FR 48535), this
rule is classified as Compatibility
Category NRC—Areas of Exclusive NRC
Regulatory Authority. The NRC program
elements in this category are those that
relate directly to areas of regulation
reserved to the NRC by the Atomic
Energy Act of 1954, as amended, or the
provisions of 10 CFR chapter I.
Therefore, compatibility is not required
for program elements in this category.
VII. Plain Writing
The Plain Writing Act of 2010 (Pub.
L. 111–274) requires Federal agencies to
write documents in a clear, concise, and
well-organized manner. The NRC has
written this document to be consistent
VerDate Sep<11>2014
21:04 Sep 04, 2024
Jkt 262001

with the Plain Writing Act as well as the
Presidential Memorandum, ‘‘Plain
Language in Government Writing,’’
published June 10, 1998 (63 FR 31885).
segmented tube assembly to define cells
for loading.
VIII. Environmental Assessment and
Finding of No Significant Impact
Under the National Environmental
Policy Act of 1969, as amended, and the
NRC’s regulations in 10 CFR part 51,
‘‘Environmental Protection Regulations
for Domestic Licensing and Related
Regulatory Functions,’’ the NRC has
determined that this direct final rule, if
adopted, would not be a major Federal
action significantly affecting the quality
of the human environment and,
therefore, an environmental impact
statement is not required. The NRC has
made a finding of no significant impact
on the basis of this environmental
assessment.
On July 18,1990 (55 FR 29181), the
NRC issued an amendment to 10 CFR
part 72 to provide for the storage of
spent fuel under a general license in
cask designs approved by the NRC. The
potential environmental impact of using
NRC-approved storage casks was
analyzed in the environmental
assessment for the 1990 final rule. The
environmental assessment for
Amendment No. 13 tiers off of the
environmental assessment for the July
18, 1990, final rule. Tiering on past
environmental assessments is a standard
process under the National
Environmental Policy Act of 1969, as
amended.
The NAC International, Inc.
MAGNASTOR® Storage System is
designed to mitigate the effects of design
basis accidents that could occur during
storage. Design basis accidents account
for human-induced events and the most
severe natural phenomena reported for
the site and surrounding area.
Postulated accidents analyzed for an
independent spent fuel storage
installation, the type of facility at which
a holder of a power reactor operating
license would store spent fuel in casks
in accordance with 10 CFR part 72, can
include tornado winds and tornadogenerated missiles, a design basis
earthquake, a design basis flood, an
accidental cask drop, lightning effects,
fire, explosions, and other incidents.
This amendment does not reflect a
significant change in design or
fabrication of the cask. Because there are
no significant design or process
changes, any resulting occupational
exposure or offsite dose rates from the
implementation of Amendment No. 13
would remain well within the 10 CFR
part 20 limits. The NRC has also
determined that the design of the cask
as modified by this rule would maintain
confinement, shielding, and criticality
control in the event of an accident.
Therefore, the proposed changes will
not result in any radiological or nonradiological environmental impacts that
significantly differ from the
environmental impacts evaluated in the
environmental assessment supporting
the July 18, 1990, final rule. There will
be no significant change in the types or
significant revisions in the amounts of
any effluent released, no significant
increase in the individual or cumulative
radiation exposures, and no significant
increase in the potential for, or
consequences from, radiological
accidents. The NRC documented its
A. The Action
The action is to amend § 72.214 to
revise the NAC International, Inc.
MAGNASTOR® Storage System listing
within the ‘‘List of approved spent fuel
storage casks’’ to include Amendment
No. 13 to Certificate of Compliance No.
1031.
B. The Need for the Action
This direct final rule amends the
certificate of compliance for the NAC
International, Inc. MAGNASTOR®
Storage System design within the list of
approved spent fuel storage casks to
allow power reactor licensees to store
spent fuel, in the form of FBM, at
reactor sites in casks with the approved
modifications under a general license.
Specifically, Amendment No. 13 revises
the certificate of compliance to add a
new type of radioactive contents (FBM
from the damaged Three Mile Island
Unit 2 reactor) to be stored inside the
MAGNASTOR® transportable storage
canister (TSC) and to include concrete
with a compressive strength of 6,000 psi
for concrete cask number 6 as an
alternate to the previously approved
8,000 psi compressive strength.
Additionally, Amendment No. 13 adds
a new design configuration of the TSC
(the FBM TSC) to accommodate the
FBM and the TSC internal components.
The new configuration includes: (1)
reducing closure lid assembly thickness
of the TSC and removing the hydrostatic
pressure test; (2) adding a new waste
basket liner (WBL) (based on the
Greater-Than-Class C Waste WBL) made
from stainless steel in lieu of the fuel
basket, for the storage of FBM inside the
FBM TSC; (3) adding a new debris
material container to be used as an
operational device to handle and house
finer debris; and (4) adding a new

Office of Management and Budget,
approval number 3150–0132.
D. Alternative to the Action
The alternative to this action is to
deny approval of Amendment No. 13
and not issue the direct final rule.
Consequently, any 10 CFR part 72
general licensee that seeks to load spent
nuclear fuel, in the form of FBM, into
NAC International, Inc. MAGNASTOR®
Storage System in accordance with the
changes described in proposed
Amendment No. 13 would have to
request an exemption from the
requirements of §§ 72.212 and 72.214.
Under this alternative, interested
licensees would have to prepare, and
the NRC would have to review, a
separate exemption request, thereby
increasing the administrative burden
upon the NRC and the costs to each
licensee. The environmental impacts
would be the same as the proposed
action.
Public Protection Notification
The NRC may not conduct or sponsor,
and a person is not required to respond
to, a request for information or an
information collection requirement
unless the requesting document
displays a currently valid Office of
Management and Budget control
number.
E. Alternative Use of Resources
Approval of Amendment No. 13 to
Certificate of Compliance No. 1031
would result in no irreversible
commitment of resources.
F. Agencies and Persons Contacted
No agencies or persons outside the
NRC were contacted in connection with
the preparation of this environmental
assessment.

G. Finding of No Significant Impact
The environmental impacts of the
action have been reviewed under the
requirements in the National
Environmental Policy Act of 1969, as
amended, and the NRC’s regulations in
subpart A of 10 CFR part 51,
‘‘Environmental Protection Regulations
for Domestic Licensing and Related
Regulatory Functions.’’ Based on the
foregoing environmental assessment, the
NRC concludes that this direct final
rule, ‘‘List of Approved Spent Fuel
Storage Casks: NAC International, Inc.
MAGNASTOR® Storage System
Certificate of Compliance No. 1031,
Amendment No. 13’’ will not have a
significant effect on the human
environment. Therefore, the NRC has
determined that an environmental
impact statement is not necessary for
this direct final rule.
IX. Paperwork Reduction Act
Statement
This direct final rule does not contain
any new or amended collections of
information subject to the Paperwork
Reduction Act of 1995 (44 U.S.C. 3501
et seq.). Existing collections of
information were approved by the

X. Regulatory Flexibility Certification
Under the Regulatory Flexibility Act
of 1980 (5 U.S.C. 605(b)), the NRC
certifies that this direct final rule will
not, if issued, have a significant
economic impact on a substantial
number of small entities. This direct
final rule affects only nuclear power
plant licensees and NAC International,
Inc. These entities do not fall within the
scope of the definition of small entities
set forth in the Regulatory Flexibility
Act or the size standards established by
the NRC (§ 2.810).
XI. Regulatory Analysis
On July 18, 1990 (55 FR 29181), the
NRC issued an amendment to 10 CFR
part 72 to provide for the storage of
spent nuclear fuel under a general
license in cask designs approved by the
NRC. Any nuclear power reactor
licensee can use NRC-approved cask
designs to store spent nuclear fuel if (1)
it notifies the NRC in advance; (2) the
spent fuel is stored under the conditions
specified in the cask’s certificate of
compliance; and (3) the conditions of
the general license are met. A list of
NRC-approved cask designs is contained
in § 72.214. On November 21, 2008 (73
FR 70587), the NRC issued an
amendment to 10 CFR part 72 that
approved the NAC International, Inc.
MAGNASTOR® Storage System design
by adding it to the list of NRC-approved
cask designs in § 72.214.
On July 13, 2022, NAC International,
Inc. submitted a request to amend
Certificate of Compliance No. 1031.
NAC International, Inc. and
supplemented its request on the
following dates: October 13, 2022,
November 30, 2022, June 27, 2023,
August 17, 2023, and September 15,
2023 (ADAMS Accession Nos.
ML22287A038, ML22321A269,
ML23178A225, ML23229A481, and
ML23258A233, respectively) as
described in Section IV ‘‘Discussion of
Changes,’’ of this document.
The alternative to this action is to
withhold approval of Amendment No.
13 and to require any 10 CFR part 72
general licensee seeking to load spent
nuclear fuel, including FBM, into the

NAC International, Inc. MAGNASTOR®
Storage System under the changes
described in Amendment No. 13 to
request an exemption from the
requirements of §§ 72.212 and 72.214.
Under this alternative, each interested
10 CFR part 72 licensee would have to
prepare, and the NRC would have to
review, a separate exemption request,
thereby increasing the administrative
burden upon the NRC and the costs to
each licensee.
Approval of this direct final rule is
consistent with previous NRC actions.
Further, as documented in the
preliminary safety evaluation report and
environmental assessment, this direct
final rule will have no adverse effect on
public health and safety or the
environment. This direct final rule has
no significant identifiable impact or
benefit on other government agencies.
Based on this regulatory analysis, the
NRC concludes that the requirements of
this direct final rule are commensurate
with the NRC’s responsibilities for
public health and safety and the
common defense and security. No other
available alternative is believed to be as
satisfactory; therefore, this action is
recommended.
XII. Backfitting and Issue Finality
The NRC has determined that the
backfit rule (§ 72.62) does not apply to
this direct final rule. Therefore, a backfit
analysis is not required. This direct final
rule revises Certificate of Compliance
No. 1031 for the NAC International, Inc.
MAGNASTOR® Storage System, as
currently listed in § 72.214. The revision
consists of the changes in Amendment
No. 13 previously described, as set forth
in the revised certificate of compliance
and technical specifications.
Amendment No. 13 to Certificate of
Compliance No. 1031 for the NAC
International, Inc. MAGNASTOR®
Storage System was initiated by NAC
International, Inc. and was not
submitted in response to new NRC
requirements, or an NRC request for
amendment. Amendment No. 13 applies
only to new casks fabricated and used
under Amendment No. 13. These
changes do not affect existing users of
the NAC International, Inc.
MAGNASTOR® Storage System, and the
current Amendment No. 12 continues to
be effective for existing users. While

II. Rulemaking Procedure
This rule is limited to the changes contained in Amendment No. 13
to Certificate of Compliance No. 1031 and does not include other
aspects of the NAC International, Inc. MAGNASTOR[supreg] Storage System
design. The NRC is using the ``direct final rule procedure'' to issue
this amendment because it represents a limited and routine change to an
existing certificate of compliance that is expected to be non-
controversial. Adequate protection of public health and safety
continues to be reasonably assured. The amendment to the rule will
become effective on November 19, 2024. However, if the NRC receives any
significant adverse comment on this direct final rule by October 7,
2024, then the NRC will publish a document that withdraws this action
and will subsequently address the comments received in a final rule as
a response to the companion proposed rule published in the Proposed
Rules section of this issue of the Federal Register or as otherwise
appropriate. In general, absent significant modifications to the
proposed revisions requiring republication, the NRC will not initiate a
second comment period on this action.
A significant adverse comment is a comment where the commenter
explains why the rule would be inappropriate, including challenges to
the rule's underlying premise or approach, or would be ineffective or
unacceptable without a change. A comment is adverse and significant if:
(1) The comment opposes the rule and provides a reason sufficient
to require a substantive response in a notice-and-comment process. For
example, a substantive response is required when:
(a) The comment causes the NRC to reevaluate (or reconsider) its
position or conduct additional analysis;
(b) The comment raises an issue serious enough to warrant a
substantive response to clarify or complete the record; or
(c) The comment raises a relevant issue that was not previously
addressed or considered by the NRC.
(2) The comment proposes a change or an addition to the rule, and
it is apparent that the rule would be ineffective or unacceptable
without incorporation of the change or addition.
(3) The comment causes the NRC to make a change (other than
editorial) to the rule, certificate of compliance, or technical
specifications.
III. Background
Section 218(a) of the Nuclear Waste Policy Act of 1982, as amended,
requires that ``[t]he Secretary [of the Department of Energy] shall
establish a demonstration program, in cooperation with the private
sector, for the dry storage of spent nuclear fuel at civilian nuclear
power reactor sites, with the objective of establishing one or more
technologies that the [Nuclear Regulatory] Commission may, by rule,
approve for use at the sites of civilian nuclear power reactors
without, to the maximum extent practicable, the need for additional
site-specific approvals by the Commission.'' Section 133 of the Nuclear
Waste Policy Act states, in part, that ``[t]he Commission shall, by
rule, establish procedures for the licensing of any technology approved
by the Commission under Section 219(a) [sic: 218(a)] for use at the
site of any civilian nuclear power reactor.''
To implement this mandate, the Commission approved dry storage of
spent nuclear fuel in NRC-approved casks under a general license by
publishing a final rule that added a new subpart K in part 72 of title
10 of the Code of Federal Regulations (10 CFR) entitled ``General
License for Storage of Spent Fuel at Power Reactor Sites'' (55 FR
29181; July 18, 1990). This rule also established a new subpart L in 10
CFR part 72 entitled ``Approval of Spent Fuel Storage Casks,'' which
contains procedures and criteria for obtaining NRC approval of spent
fuel storage cask designs. The NRC subsequently issued a final rule on
November 21, 2008 (73 FR 70587), that approved the NAC International,
Inc. MAGNASTOR[supreg] Storage System design and added it to the list
of NRC-approved cask designs in Sec. 72.214 as Certificate of
Compliance No. 1031.
IV. Discussion of Changes
On July 13, 2022, NAC International, Inc. submitted a request to
the NRC to amend Certificate of Compliance No. 1031. NAC International,
Inc. and supplemented its request on the following dates: October 13,
2022, November 30, 2022, June 27, 2023, August 17, 2023, and September
15, 2023 (ADAMS Accession Nos. ML22287A038, ML22321A269, ML23178A225,
ML23229A481, and ML23258A233, respectively).
Amendment No. 13 revises the certificate of compliance to add a new
type of radioactive contents (fuel bearing material (FBM) from the
damaged Three Mile Island Unit 2 reactor) to be stored inside the
MAGNASTOR[supreg] transportable storage canister (TSC) and to include
concrete with a compressive strength of 6,000 psi for concrete cask
number 6 as an alternate to the previously approved 8,000 psi
compressive strength. Additionally, Amendment No. 13 adds a new design
configuration of the TSC (the FBM TSC) to accommodate the FBM and the
TSC internal components. The new configuration includes: (1) reducing
closure lid assembly thickness of the TSC and removing the hydrostatic
pressure test; (2) adding a new waste basket liner (WBL) (based on the
Greater-Than-Class C Waste WBL) made from stainless steel in lieu of
the fuel basket for the storage of FBM inside the FBM TSC; (3) adding a
new debris material container to be used as an operational device to
handle and house finer debris; and (4) adding a new segmented tube
assembly to define cells for loading.
As documented in the preliminary safety evaluation report, the NRC
performed a safety evaluation of the proposed certificate of compliance
amendment request. The NRC determined that this amendment does not
reflect a significant change in design or fabrication of the cask.
Specifically, the NRC determined that the design of the cask would
continue to maintain confinement, shielding, and criticality control in
the event of each evaluated accident condition. In addition, any
resulting occupational exposure or offsite dose rates from the
implementation of Amendment No. 13 would remain well within the limits
specified by 10 CFR part 20, ``Standards for Protection Against
Radiation.'' Therefore, the NRC found there will be no significant
change in the types or amounts of any effluent released, no significant
increase in the individual or cumulative radiation exposure, and no
significant increase in the potential for or consequences from
radiological accidents.
The NRC staff determined that the amended NAC International, Inc.
MAGNASTOR[supreg] Storage cask design, when used under the conditions
specified in the certificate of compliance, the technical
specifications, and the NRC's regulations, will meet the requirements
of 10 CFR part 72; therefore, adequate protection of public health and
safety will continue to be reasonably assured. When this direct final
rule becomes effective, persons who hold a general license under Sec.
72.210 may, consistent with the license conditions under Sec. 72.212,
load spent nuclear fuel, in the form of FBM, into NAC International,
Inc. MAGNASTOR[supreg] Storage System cask design that meet the
criteria of Amendment No. 13 to Certificate of Compliance No. 1031.
The NRC is clarifying that Amendment 13 to Certificate of
Compliance No. 1031 does not involve
[[Page 72301]]
storage of spent fuel assemblies as is the case for most certificate of
compliance applications. Rather, this amendment involves storage of
FBM, which includes components associated with deposited fuel and
fission products from the damaged Three Mile Island Unit 2 reactor,
inside the transportable storage canister. This amendment also involves
adding a new design configuration of the transportable storage canister
to accommodate the FBM and the new transportable storage canister
internal components. A waste basket liner is proposed to replace the
fuel basket structure for storage of FBM. Because this configuration
involves only deposited fuel and fission products rather than entire
spent fuel assemblies, the storage of the materials is of lower risk
significance than that of the storage of spent fuel assemblies. The
NRC's safety evaluation considered the design changes proposed for this
amendment and concluded that they meet the requirements of 10 CFR part
72.
V. Voluntary Consensus Standards
The National Technology Transfer and Advancement Act of 1995 (Pub.
L. 104-113) requires that Federal agencies use technical standards that
are developed or adopted by voluntary consensus standards bodies unless
the use of such a standard is inconsistent with applicable law or
otherwise impractical. In this direct final rule, the NRC revises the
NAC International, Inc. MAGNASTOR[supreg] Storage Cask System design
listed in Sec. 72.214, ``List of approved spent fuel storage casks.''
This action does not constitute the establishment of a standard that
contains generally applicable requirements.
VI. Agreement State Compatibility
Under the ``Agreement State Program Policy Statement'' approved by
the Commission on October 2, 2017, and published in the Federal
Register on October 18, 2017 (82 FR 48535), this rule is classified as
Compatibility Category NRC--Areas of Exclusive NRC Regulatory
Authority. The NRC program elements in this category are those that
relate directly to areas of regulation reserved to the NRC by the
Atomic Energy Act of 1954, as amended, or the provisions of 10 CFR
chapter I. Therefore, compatibility is not required for program
elements in this category.
VII. Plain Writing
The Plain Writing Act of 2010 (Pub. L. 111-274) requires Federal
agencies to write documents in a clear, concise, and well-organized
manner. The NRC has written this document to be consistent with the
Plain Writing Act as well as the Presidential Memorandum, ``Plain
Language in Government Writing,'' published June 10, 1998 (63 FR
31885).
VIII. Environmental Assessment and Finding of No Significant Impact
Under the National Environmental Policy Act of 1969, as amended,
and the NRC's regulations in 10 CFR part 51, ``Environmental Protection
Regulations for Domestic Licensing and Related Regulatory Functions,''
the NRC has determined that this direct final rule, if adopted, would
not be a major Federal action significantly affecting the quality of
the human environment and, therefore, an environmental impact statement
is not required. The NRC has made a finding of no significant impact on
the basis of this environmental assessment.
A. The Action
The action is to amend Sec. 72.214 to revise the NAC
International, Inc. MAGNASTOR[supreg] Storage System listing within the
``List of approved spent fuel storage casks'' to include Amendment No.
13 to Certificate of Compliance No. 1031.
B. The Need for the Action
This direct final rule amends the certificate of compliance for the
NAC International, Inc. MAGNASTOR[supreg] Storage System design within
the list of approved spent fuel storage casks to allow power reactor
licensees to store spent fuel, in the form of FBM, at reactor sites in
casks with the approved modifications under a general license.
Specifically, Amendment No. 13 revises the certificate of compliance to
add a new type of radioactive contents (FBM from the damaged Three Mile
Island Unit 2 reactor) to be stored inside the MAGNASTOR[supreg]
transportable storage canister (TSC) and to include concrete with a
compressive strength of 6,000 psi for concrete cask number 6 as an
alternate to the previously approved 8,000 psi compressive strength.
Additionally, Amendment No. 13 adds a new design configuration of the
TSC (the FBM TSC) to accommodate the FBM and the TSC internal
components. The new configuration includes: (1) reducing closure lid
assembly thickness of the TSC and removing the hydrostatic pressure
test; (2) adding a new waste basket liner (WBL) (based on the Greater-
Than-Class C Waste WBL) made from stainless steel in lieu of the fuel
basket, for the storage of FBM inside the FBM TSC; (3) adding a new
debris material container to be used as an operational device to handle
and house finer debris; and (4) adding a new segmented tube assembly to
define cells for loading.
C. Environmental Impacts of the Action
On July 18,1990 (55 FR 29181), the NRC issued an amendment to 10
CFR part 72 to provide for the storage of spent fuel under a general
license in cask designs approved by the NRC. The potential
environmental impact of using NRC-approved storage casks was analyzed
in the environmental assessment for the 1990 final rule. The
environmental assessment for Amendment No. 13 tiers off of the
environmental assessment for the July 18, 1990, final rule. Tiering on
past environmental assessments is a standard process under the National
Environmental Policy Act of 1969, as amended.
The NAC International, Inc. MAGNASTOR[supreg] Storage System is
designed to mitigate the effects of design basis accidents that could
occur during storage. Design basis accidents account for human-induced
events and the most severe natural phenomena reported for the site and
surrounding area. Postulated accidents analyzed for an independent
spent fuel storage installation, the type of facility at which a holder
of a power reactor operating license would store spent fuel in casks in
accordance with 10 CFR part 72, can include tornado winds and tornado-
generated missiles, a design basis earthquake, a design basis flood, an
accidental cask drop, lightning effects, fire, explosions, and other
incidents.
This amendment does not reflect a significant change in design or
fabrication of the cask. Because there are no significant design or
process changes, any resulting occupational exposure or offsite dose
rates from the implementation of Amendment No. 13 would remain well
within the 10 CFR part 20 limits. The NRC has also determined that the
design of the cask as modified by this rule would maintain confinement,
shielding, and criticality control in the event of an accident.
Therefore, the proposed changes will not result in any radiological or
non-radiological environmental impacts that significantly differ from
the environmental impacts evaluated in the environmental assessment
supporting the July 18, 1990, final rule. There will be no significant
change in the types or significant revisions in the amounts of any
effluent released, no significant increase in the individual or
cumulative radiation exposures, and no significant increase in the
potential for, or consequences from, radiological accidents. The NRC
documented its
[[Page 72302]]
safety findings in the preliminary safety evaluation report.
D. Alternative to the Action
The alternative to this action is to deny approval of Amendment No.
13 and not issue the direct final rule. Consequently, any 10 CFR part
72 general licensee that seeks to load spent nuclear fuel, in the form
of FBM, into NAC International, Inc. MAGNASTOR[supreg] Storage System
in accordance with the changes described in proposed Amendment No. 13
would have to request an exemption from the requirements of Sec. Sec.
72.212 and 72.214. Under this alternative, interested licensees would
have to prepare, and the NRC would have to review, a separate exemption
request, thereby increasing the administrative burden upon the NRC and
the costs to each licensee. The environmental impacts would be the same
as the proposed action.
E. Alternative Use of Resources
Approval of Amendment No. 13 to Certificate of Compliance No. 1031
would result in no irreversible commitment of resources.
F. Agencies and Persons Contacted
No agencies or persons outside the NRC were contacted in connection
with the preparation of this environmental assessment.
G. Finding of No Significant Impact
The environmental impacts of the action have been reviewed under
the requirements in the National Environmental Policy Act of 1969, as
amended, and the NRC's regulations in subpart A of 10 CFR part 51,
``Environmental Protection Regulations for Domestic Licensing and
Related Regulatory Functions.'' Based on the foregoing environmental
assessment, the NRC concludes that this direct final rule, ``List of
Approved Spent Fuel Storage Casks: NAC International, Inc.
MAGNASTOR[supreg] Storage System Certificate of Compliance No. 1031,
Amendment No. 13'' will not have a significant effect on the human
environment. Therefore, the NRC has determined that an environmental
impact statement is not necessary for this direct final rule.
IX. Paperwork Reduction Act Statement
This direct final rule does not contain any new or amended
collections of information subject to the Paperwork Reduction Act of
1995 (44 U.S.C. 3501 et seq.). Existing collections of information were
approved by the Office of Management and Budget, approval number 3150-
0132.
Public Protection Notification
The NRC may not conduct or sponsor, and a person is not required to
respond to, a request for information or an information collection
requirement unless the requesting document displays a currently valid
Office of Management and Budget control number.
X. Regulatory Flexibility Certification
Under the Regulatory Flexibility Act of 1980 (5 U.S.C. 605(b)), the
NRC certifies that this direct final rule will not, if issued, have a
significant economic impact on a substantial number of small entities.
This direct final rule affects only nuclear power plant licensees and
NAC International, Inc. These entities do not fall within the scope of
the definition of small entities set forth in the Regulatory
Flexibility Act or the size standards established by the NRC (Sec.
2.810).
XI. Regulatory Analysis
On July 18, 1990 (55 FR 29181), the NRC issued an amendment to 10
CFR part 72 to provide for the storage of spent nuclear fuel under a
general license in cask designs approved by the NRC. Any nuclear power
reactor licensee can use NRC-approved cask designs to store spent
nuclear fuel if (1) it notifies the NRC in advance; (2) the spent fuel
is stored under the conditions specified in the cask's certificate of
compliance; and (3) the conditions of the general license are met. A
list of NRC-approved cask designs is contained in Sec. 72.214. On
November 21, 2008 (73 FR 70587), the NRC issued an amendment to 10 CFR
part 72 that approved the NAC International, Inc. MAGNASTOR[supreg]
Storage System design by adding it to the list of NRC-approved cask
designs in Sec. 72.214.
On July 13, 2022, NAC International, Inc. submitted a request to
amend Certificate of Compliance No. 1031. NAC International, Inc. and
supplemented its request on the following dates: October 13, 2022,
November 30, 2022, June 27, 2023, August 17, 2023, and September 15,
2023 (ADAMS Accession Nos. ML22287A038, ML22321A269, ML23178A225,
ML23229A481, and ML23258A233, respectively) as described in Section IV
``Discussion of Changes,'' of this document.
The alternative to this action is to withhold approval of Amendment
No. 13 and to require any 10 CFR part 72 general licensee seeking to
load spent nuclear fuel, including FBM, into the NAC International,
Inc. MAGNASTOR[supreg] Storage System under the changes described in
Amendment No. 13 to request an exemption from the requirements of
Sec. Sec. 72.212 and 72.214. Under this alternative, each interested
10 CFR part 72 licensee would have to prepare, and the NRC would have
to review, a separate exemption request, thereby increasing the
administrative burden upon the NRC and the costs to each licensee.
Approval of this direct final rule is consistent with previous NRC
actions. Further, as documented in the preliminary safety evaluation
report and environmental assessment, this direct final rule will have
no adverse effect on public health and safety or the environment. This
direct final rule has no significant identifiable impact or benefit on
other government agencies. Based on this regulatory analysis, the NRC
concludes that the requirements of this direct final rule are
commensurate with the NRC's responsibilities for public health and
safety and the common defense and security. No other available
alternative is believed to be as satisfactory; therefore, this action
is recommended.
XII. Backfitting and Issue Finality
The NRC has determined that the backfit rule (Sec. 72.62) does not
apply to this direct final rule. Therefore, a backfit analysis is not
required. This direct final rule revises Certificate of Compliance No.
1031 for the NAC International, Inc. MAGNASTOR[supreg] Storage System,
as currently listed in Sec. 72.214. The revision consists of the
changes in Amendment No. 13 previously described, as set forth in the
revised certificate of compliance and technical specifications.
Amendment No. 13 to Certificate of Compliance No. 1031 for the NAC
International, Inc. MAGNASTOR[supreg] Storage System was initiated by
NAC International, Inc. and was not submitted in response to new NRC
requirements, or an NRC request for amendment. Amendment No. 13 applies
only to new casks fabricated and used under Amendment No. 13. These
changes do not affect existing users of the NAC International, Inc.
MAGNASTOR[supreg] Storage System, and the current Amendment No. 12
continues to be effective for existing users. While current users of
this storage system may comply with the new requirements in Amendment
No. 13, this would be a voluntary decision on the part of current
users.
For these reasons, Amendment No. 13 to Certificate of Compliance
No. 1031 does not constitute backfitting under Sec. 72.62 or Sec.
50.109(a)(1), or otherwise
[[Page 72303]]
represent an inconsistency with the issue finality provisions
applicable to combined licenses in 10 CFR part 52. Accordingly, the NRC
has not prepared a backfit analysis for this rulemaking.
XIII. Congressional Review Act
This direct final rule is not a rule as defined in the
Congressional Review Act.
